Killer Croc has always been more of a fear villain rather than one that makes much sense. Supposedly afflicted with an over-keratinizing skin condition which gives him scaly skin, he suffered abuse and trauma that created a rage which led to..cannibalism! ok!
Eventually, he leads his criminal life into being a cannibal hitman for mobs and becomes one of the eight assassins hired to kill Batman in Arkham Origins. His battle there was a pretty sequential boss fight that requires some waiting and timing. Later he escapes Arkham Asylum and Batman has to race on floating rafts in the sewers to get to a goal while Killer Croc will suddenly rush and attack, forcing the player to throw a Batarang that activates his old shock collar to temporarily subdue him.
Later he is captured, and in Arkham Knight is heavily experimented on to test his regenerative abilities but it has a negative effect that accelerates his mutation to the point where he grows a tale and becomes more croc like in every way. If they had made a figure of THAT version I would have also bought it.
The figure is pretty good considering Multiverse, except for recent history, uses DC Classic joints
and poseability. That paint is not bad, though the finish is very gloss-heavy. The articulation isn't anything to write home about, but it's good enough. The head sticks out from his massive shoulders, so it's not possible to turn it without giving him a rather unnatural look. I can say one thing though, despite his mediocrity, he was very cheap! Even compared to his original MRSP. He's also still better than Suicide Squad Killer Croc by miles.
